FDA Removes Forced-air Recommendation Letter

You’ve wanted to stop blowing air anyway. Now is the time to switch to air-free HotDog Patient Warming! In August 2017, the FDA –addressing clinician concern about the safety of forced-air patient warming (FAW)—issued a Letter to Healthcare Providers, assuring them that FAW was safe. That letter has been removed from the FDA site. All links to the FAW Letter are dead. A search of the entire FDA database, including Letters to Industry (Medical Devices) reveals no Letter. All traces of the Letter seems to have been wiped from the FDA Archive—which should contain all historic documents. Curious…although recent events regarding 3M’s [...]

ERAS: forced-air warming not recommended in H&K replacement surgery

The Enhanced Recovery After Surgery (ERAS)-compliant normothermia protocol for hip or knee replacement surgery urges maintenance of normal body temperature, but also includes the following statement: “However, the use of forced air-warming is not recommended as there is evidence that this is associated with an increased risk of infection (McGovern et al. 2011, Koc et al. 2017).” >Read More Implement an ERAS-compliant protocol with effective air-free HotDog patient warming.

Treating Hypothermia During Liver Transplant Surgery

Dr. Scott Lindberg, Director of Liver Transplant Anesthesia at Houston Methodist Hospital, shares his experiences with treating hypothermia in one of the most difficult patient populations for inadvertent hypothermia: the liver transplant patient. Dr. Lindberg has had great success with the HotDog Patient Warming System. There are two video options: 1) a short version with just the highlights, and 2) longer version filled with specific recommendations to help you get the best outcomes. Thanks for watching!

3M Attempts to Mislead Federal Judge With Erroneous Study Conclusions

3M Attempts to Mislead Federal Judge With Erroneous Study Conclusions: Previously published data contradict conclusions of the Jeans study Click here for the full analysis (PDF) In a recent study pre-published online by Jeans et al, the authors conclude that screening for methicillin sensitive staphylococcus aureus (MSSA) and treating those that test positive before surgery significantly reduces periprosthetic joint infection (PJI) rates. However, McGovern and Reed previously reported published and unpublished data from one of the three hospitals in the study that directly contradicts the Jeans’ conclusions.  Jeans did not account for the confounding effect caused by the switch from Bair [...]

3M Wins First Bair Hugger Case; 8 More Cases Prepare For Trial

The first question to the jury, in summary: “Did plaintiff prove that Bair Hugger was unreasonably dangerous and that a safe alternative was available?” The alternative, the Court ruled, had to be another air-blowing device to meet defective design requirements (it could not be HotDog®, another electric warming system, or a water-based system). The jury’s answer: “No.” With that, the jury determined that 3M’s Bair Hugger patient warming device would not be held responsible for a South Carolina man’s orthopedic infection. The trial of 76-year-old Louis Gareis’s claim was the first of more than 4,500 cases filed against Bair Hugger in [...]

Journal of Hospital Infection: Forced-Air Warming An Infection-Control “Hazard” in Implant Surgery recently submitted a press release regarding a review article published by Journal of Hospital Infection.  The press release is as follows: Surgical-infection experts have unambiguously concluded that forced-air warming “...does contaminate ultra-clean air ventilation….” in the operating room. Their advice: Use air-free warming during implant surgery. PRLog - Nov. 12, 2014 - MINNEAPOLIS -- “Infection Control Hazards Associated with the Use of Forced-air Warming in Operating Theatres," appears in the scientific publication of the Healthcare Infection Society, Journal of Hospital Infection. The article, in press, can be found on-line here. The authors, including surgeon D.L. Leaper, chair of the committee that drafted the UK’s surgical-site infection guidelines, summarized the [...]

Patient Advocate Warns Against Forced-Air Warming

A well-known patient advocate now urges surgical patients to avoid forced-air warming—even to change hospitals if necessary. The advocate, Rosie Bartel, speaks from experience. Infected with MRSA during a knee-replacement procedure at a hospital using forced-air warming, Bartel has undergone 27 subsequent operations— including amputation of her leg to the hip. The MRSA remains active. After researching how the pathogens rose from the floor of the operating room into the sterile field, Bartel concluded that Bair Hugger warming blew particles into her wound, causing the MRSA infection. Bartel has a website ( to share her findings and give her advice to patients. Click on [...]

Infection Risk from Forced-air Warming Considered; Study on Bacterial Contamination Recommended

International Orthopedic Consensus “We recognize the theoretical risk posed by forced air warming blankets,” concluded the Consensus Statement recently released by the International Consensus on Periprosthetic Joint Infection. While not urging a change in practice, the Consensus Statement recommended that further studies be undertaken regarding the safety of forced-air warming (“FAW”) in orthopedic implant surgery. Delegates from more than 50 countries and 80 different societies met in August 2013 to evaluate scientific literature and identify areas for further research. Among the other conclusions relating to periprosthetic joint infections and the risk of airborne contamination: 1. Airborne particulate bacteria are a major [...]

Nursing Journal: Forced-Air Warmers May Allow Pathogens to Contact Surgical Wounds

AORN Journal, noting concerns about infection risk from forced-air warmers, called for multi-center, randomized, controlled trials. Evidence of bacteria in the air-flow paths of forced-air warmers; authors ask manufacturers to consider redesign. In a continuing-education review article in the October issue of AORN Journal,published by the Association of Operating Room Nurses, the authors examined 192 sources.  Their conclusions included the following: “Clinicians should take steps to prevent health care–associated infections from the use of forced-air warmers….”  Such steps include “routinely and meticulously” cleaning the devices.  Forced-air warmers may interrupt the flow of filtered air toward the area of the wound and may [...]
